Re: Anycast provider for SMTP?

Any luck on a DNS based solution? On Mon, Jun 15, 2015 at 12:50 PM, Joe Hamelin <joe@nethead.com> wrote:

I have a mail system where there are two MX hosts, one in the US and one in Europe. Both have a DNS MX record metric of 10 so a bastardized round-robin takes place. This does not work so well when one site goes down. My solution will be to place a load balancer in a hosting site (virtual, of course) and have it provide HA. But what about HA for the LB? At first glance anycasting would seem to be a great idea but there is a problem of broken sessions when routes change.

Have any of you seen something like this work in the wild?
